Selection and installation

Check stroke, energy per cycle and hourly energy together with impact speed, cycle rate, driving force and available installation space. Use external adjustment to match the application; confirm the contact accessory and mounting thread for this model.

Series working principle

The piston forces oil through metering passages to dissipate impact energy. Turning the adjustment knob changes the effective flow area; the return mechanism resets the piston after the load is removed.

Catalog application and mounting notes

EK42x75 is an adjustable hydraulic shock absorber with a published 75 mm stroke and M42 × 1.5 mounting thread. The catalog separates the base dimensions from the CM(S) mounting configuration; verify the drawing context and installation envelope before ordering.

Temperature ranges are series catalog references. Confirm the fluid, seals and ordered configuration; an optional range is not a standard-model rating.

Replacement candidates for referenced models

Model-number relationships are recommendations only. Final selection must be based on the actual operating conditions, mounting and application review.
